A multi-information fusion system and method for a combine harvester separating device

Abstract

The invention relates to a multi-information fusion system for a combine harvester separation device, which includes an embedded processor, a combine harvester separation device and a sensor network. One end of the sensor network is connected to the separation device for collecting combine harvester separation devices. The operating parameters of the device; the multi-information fusion technology of the combine harvester separation device combines the agricultural production field with the Internet of Things, uses wireless sensor networks to collect the operating parameters of the combine harvester, and uses sensor adaptive weighted fusion algorithms, which can be flexibly , Fast and real-time completion of all functions of the load feedback automatic control device of the splitting device of the combine harvester.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multi-information fusion system and method for a detaching device of a combine harvester. Background technique [0002] As an important agricultural production device, the combine harvester is widely used in my country's agricultural production, which not only greatly reduces the labor intensity of farmers, but also effectively improves production efficiency. At present, when the combine harvester is working in the field, it can only be operated by the driver The operator judges the condition of the field by feeling, and cannot adjust the working state of the combine harvester in time, and it is prone to failures such as drum blockage caused by excessive load, resulting in low working efficiency of the harvester. Control is imperative. The operating load of the separating device of the combine varies randomly with factors such as feeding amount, driving speed, drum rotation...

AI Technical Summary

Problems solved by technology

This kind of operation method requires high level of operator driving, high labor intensity, it is difficult to reduce the failure rate, and the operation speed and operation efficiency are low; (2) a small number of combine harvesters mainly use PID or fuzzy control for the separation device drum. Carry out single control, the operation parameter of the combine harvester that this method collects basis is single, the actual control effect of the optimal operation parameter result obtained is not ideal, and if PID or fuzzy control fails; it can be seen that the above control methods are all unilateral Controlling the operation of the combine harvester does not take into account the actual operating state of the combine harvester, and the existing combine harvester lacks a comprehensive and effective automatic control device for the load
